What is Overclocking?

To put it very simply, overclocking is making your computer, or a certain component, run faster than the manufacturer set it to when it left the factory.

Why should I overclock my computer?

Again, to put it simply, the idea behind overclocking your computer is to get a free performance increase. The processes involved in overclocking are now very simple, and more speed is literally at your fingertips. A while ago, overclocking was limited to just increasing the CPU speed, but now there are a myriad of options to alter in the quest for more speed. One of the best ways to obtain more speed is through video card overclocking, and even small adjustments to the speed of the card can give reasonable frame rate increases.

What are the problems associated with overclocking?

There are three main problems associated with overclocking, and two of these can be removed if you are sensible in undertaking the overclocking. The first of these is the most serious in many people's minds, and is the one that can't be eliminated. By overclocking your video card, you are actually voiding the warranty supplied by the manufacturer. The second problem associated with overclocking, both with CPU's and with video cards, is heat. If your computer is too hot, it either won't work properly, or won't work at all. Thankfully this problem is easily fixed, and this guide looks at cooling in a bit of detail. The third problem associated with overclocking video cards are things called artifacts. They are weird graphical glitches which signify you have a serious problem. Again, these can easily be fixed.
